Patented June 15, 1909.

Application filed July 28, 1908. Serial No. 445,786.

To all whom it may concern:

Be it known that I, JAMES H. CoLenovn, a citizen of the United States of America, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Plastic Com ounds for Making Burial-Vaults, of which t e following is a specification.

This invention relates to plastic comounds for making burial vaults and for simiar purposes, and one of the (princi a1 objects of t 1e invention is to provi e a p astic com pound which may be molded into roper shape to provide a burial vault whic shall be strong and durable and which will permit the drivin of the nails or the attachment of screws or handles thereto.

Another object of the invention is to provide a plastic material for the manufacture of burial vaults and similar devices which can be reinforced by embedded rods or stakes, which will be ca able of being sealed to render the vaultairetlght and in which the latter may be Eovered with cloth tacked to the surface.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which,

Figure 1 is a pers ective view of the top or cover for the van t. Fig. 2 is a perspective view of the body of the vault with the cover removed. Fig. 3 is a side elevation of the vault complete and showing in dotted lines the longitudinal reinforcing rods. Fi 4 is a transverse sectional view taken throng the vault with the cover secured in lace. Fig. 5 is an enlarged detail sectional view of one corner of the vault.

Referring to the drawing, the numeral 1 designates the body of the vault which is composed of a moldable lastic material 2 comprising excelsio; marb e dust, magnesg Portland cement and water in suitable propor 1011, mixe and mo e mto the form of a vault, as shown. The outer and inner surfaces of the vault body are coated with cement to form a lining 3 and a covering 4. Embedded within the body portion of the vault are longitudinal reinforcing rods 5 which give great strength and durability to the artlcle. The longitudinal rods 5 are bent downwardly at their opposite ends, as.at 6, and extended laterally to brace the ends of the vault. The upper edge of the vault body is provided with a groove 7, and the top or cover 8 is provided with a rectangular flange 9 havin in its lower edge a bead 10 which fits in the groove 7 and forms a practically air and water tight joint. The p terial of which the body portion of the vault is composed will ermit the attachment of nails or tacks, so t at the vault may be covered with cloth, if found desirable, and suitable handles may be attached by forming holes through the body portion of the vault. Attaching screws 1 1 ma extend through the cover 8 and into the ody portion of the vault.

A vault made of the materials referred to may be readily coated with aint or varnish to finish the same, and is urable, air and water ti ht and can be manufactured at a reasonab e figure.

I claim A lastic compound for the production of buriall vaults composed of Pqtlanicement, excglsior, marble dust, magnesia SLQQ EfitGI mixed. ether m suit ahleqpibportions.
